Inking process   Ink Hue And Matters Needing Attention Before Printing

 Master the system, color, color saturation, viscosity, fineness and other indicators of the ink used.  Ink Hue And Matters Needing Attention Before Printing

       Examine and approve the sample, customer requirements, process requirements, hue requirements and ink use requirements, and have an in-depth understanding of the arrangement of color sequence of each color group, the number of prints of the product, the amount of ink and the allocation of main colors.Ink Hue And Matters Needing Attention Before Printing

       The solubility of diluent and ink resin, temperature deviation and the ratio of diluent are related. If the temperature is high, the diluent shall be slow drying type.Ink Hue And Matters Needing Attention Before Printing

        At the same time, the dissolution effect and volatilization speed also play a very important role in the printing quality of products. Therefore, appropriate diluents should be selected according to relevant conditions.Ink Hue And Matters Needing Attention Before Printing

 Make preparations for ink and diluent before printing.Ink Hue And Matters Needing Attention Before Printing

       During the short time of start-up overprint, the primary color ink shall be properly used according to the color matching, the proportion shall be grasped, and the hue of each color group ink shall be adjusted according to the sample, so that the sample effect can be achieved after the printing speed is stable. Ink Hue And Matters Needing Attention Before Printing

       In normal printing, batch control of the same hue is difficult for ink mixing personnel. For example, the amount of diluent will affect the color effect to varying degrees, which requires ink mixing personnel to have a strong sense of responsibility.Ink Hue And Matters Needing Attention Before Printing

Ink mixing precautions  Ink Hue And Matters Needing Attention Before Printing  

1. When the color tone meets the requirements, the less color types of ink used, the easier it is to allocate and control. If you can use intermediate ink, do not use multi-color ink.Ink Hue And Matters Needing Attention Before Printing

        According to the subtraction method, the more colors the spot color ink uses, the lower its saturation will be, and the black component will increase accordingly.Ink Hue And Matters Needing Attention Before Printing

       Confirm the main color and the auxiliary color contained in the printed matter. The main color ink is used as the basic ink, and other inks are used as the toner ink. Ink Hue And Matters Needing Attention Before Printing

      The basic ink is mainly used, supplemented by the toner ink, so that the spot color ink can be prepared faster and more accurately.Ink Hue And Matters Needing Attention Before Printing

     When preparing proofing and small sample ink, try to use the same paper as the paper used for printing, because the ink color will change with the difference of paper absorption and other factors. Ink Hue And Matters Needing Attention Before Printing

      Only by maintaining a stable paper can we avoid the color error caused by the difference of paper.Ink Hue And Matters Needing Attention Before Printing

      Make small samples or scrape samples with ordinary white cardboard. The thickness of the ink layer will directly affect the color of the ink. If the ink layer is thin, the color is light and the brightness is high. Ink Hue And Matters Needing Attention Before Printing

       The difference of color will be caused by the difference of field or screen cable, wet pressing or wet drying, large or small amount of powder spraying, flatness and whiteness of paper surface, thickness of ink layer and so on.Ink Hue And Matters Needing Attention Before Printing

      To adjust the spot color ink, first transfer the saturated hue of the ink, make a thin sample, confirm that there is no lack of main and auxiliary colors, and then adjust it to the required spot color with diluent.Ink Hue And Matters Needing Attention Before Printing

      The factors affecting the color of spot color ink also include printing process, water and ink volume control, vehicle speed and printing equipment. We should grasp the printing and its laws to ensure product quality.Ink Hue And Matters Needing Attention Before Printing

       Mastering the allocation of spot color ink, the control of ink dosage and the full utilization of residual ink can not only save materials, but also improve personal quality and technical level. Ink Hue And Matters Needing Attention Before Printing

      An excellent ink mixer plays an important role in the development of new ink, color innovation and the reduction of ink cost.Ink Hue And Matters Needing Attention Before Printing
